BRAKE BEAM.

SPECIFICATION forming part of Letters Patent No. 713,783, dated November18, 1902.

Application led July30,1902.

,To all whom 'ift ntfty concern.-

Beit known that I, CHARLES V. MARQUART, a citizen of the United States,residing at Sandusky, in the county of Erie and State of Ohio, haveinvented certain new and useful Improvements in Brake-Beams; and l dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to brake-beams and the devices attached thereto;and it consists in the construction and combination of parts hereinaftermore particularly set forth and claimed.

Figure l represents a side elevation of a brake-beam and detached partsembodying my invention, but Without the brakes, the View being takenfrom the side which the brakes would occupy. Fig. 2 represents alongitudinal section through the same on the line 2 2 of Fig. l. Fig. 3represents an end view of one of the sleeves or ferrules. Fig. 4represents a vertical sectional vieW of one of the brakes from one side.Fig. 5 represents a detail front elevation of the face of the brake-headto which the brake-shoe is to be attached.

A designates a tubular brake-beam. B designates tvvo sleeves or ferrulesfitted upon the ends thereof, each of said ferrules being provided withan internal annular shoulder b, fitting against the proximate end of thesaid beam, also with a terminal brake-shoe cup consisting of twoparallel disks or cheeks B and B2 and a trough-shaped connecting-pieceB3, also with an external lug U, having a central hole. All these partsof the ferrule or sleeve are integral therewith. The disks or cheeks BB2 are centrally perforated,as shown of a pin D, which passes through ahole e in a lobe E of the brake-head E, to Which the brakeshoe F isattached. The open sides of the cups aforesaid are of course presentedtoward the Wheels, so that the brake-shoes may bear against theperipheries of the latter. Each pin D has a slot D through its end toreceive a transverse key or Wedge D2 for holding said pin in place.

On the middle part of the bar A is sleeved a stud or short arm G, whichextends in the Serial No. 117.631. (No model.)

same direction as the brake-shoes and has in its end away from said beaman eye g, the bore of which is slightly curved to receive the middlepart of a bent truss or brace-rod H, the ends of which pass throughholes in the lugs b' aforesaid and are screw-threaded to receive nuts 7bfor fastening the brake rod and .beam tightly together. By tightening orloosening these nuts expansion and contraction due to changes oftemperature may be compensated for. They also provide for easyseparation of all the parts when desired.

All the parts above described are of strong malleable metal. In puttingthem together the stud is first slipped on the beam to the middlethereof, the sleeves or ferrules are then driven on the ends of the saidbeam, the brace-bar is passed through the eye of the stud, the ends ofthe said brace-bar are passed through the lugs on the sleeves, the nutsare turned home, the brake-heads With the shoes attached are `introducedinto the cups with their perforated lobes in position to receive thepins, the pins are passed through said disks and lobes, and the Wedgesare passed transversely through the said slots in the said disks. Thereverse procedure is followed in taking apart the brake-beam andattachments.

The brake-heads are Yfree to turn on the pins, thereby allowing theshoes to adjust themselves to the wheels and preserve a perfectfia-While keeping the wear even.

A brake-beam and attachments of the above construction are cheaply made,durable, capable of resisting great strain, and very easily cleaned orrepaired. The sleeve having an external perforated lug, an internalannular shoulder, and a terminal brake-cup, all integral, is aparticularly strong, simple, and useful feature combined as stated. Thebeam A may be slightly arched, if preferred, in* stead of straight, asshown.

Having thus described my invention, what I claim as new, and desire tosecu re by Letters Patent, is

l. In combination with a brake -beam, a stud sleeved thereon andprovided at its farther end with an eye, a brace-rod having its middlepart in said eye and a pair of sleeves each provided with means forholding a brake head and shoe and also having an internal IOO shoulderdistinct from the end of the sleeve and fitting against the end of saidbeam and an external perforated lug, the ends of the said brace-barbeing passed through the said lugs and secured there for the purpose setforth. t

2. In combination with a brake-beam a pair of ferrules fitted on itsends, each having integral with it an external perforated lug aninternal annular shoulder fitting against the end of the said beam and aterminal brakeholding cup consisting of a pair of perforated disks orcheeks and a eonnectin g part, abracey rod fastened to said lug at itsends and having its middle part in the eye of the said stud, brake-headshaving perforated parts set into the said cups and pins passing throughthe
